[0029] See also Figures 1 to 5 The embodiment of the present application provides a feeding device, including a first material picking structure 30, a material moving structure 10 and a conveying structure, wherein a first station and a second station are provided on both sides of the conveying structure, the first station is used to store a first material 200, the conveying structure is used to drive the material moving structure 10 to move back and forth between the first station and the second station, the material moving structure 10 is used to grab the first material 200, the second station is used to store a second material 300 and to receive the first material 200 grabbed by the material moving structure 10, the first material picking structure 30 is arranged at the second station and is located above the second material 300, the first material picking structure 30 is used to grab the second material 300 and drive the second material 300 to rise and fall, and the material moving structure 10 is also used to receive the second material 300 at the first material picking structure 30 to drive the second material 300 to move to the first station.

[0030] The feeding device of the present application drives the material moving structure 10 to move back and forth between the first station and the second station by setting up a transmission structure. The material moving structure 10 can grab the first material 200 at the first station and transfer it to the second station, and receive the second material 300 at the second station and then return to the first station. Therefore, the present application can complete loading and unloading at the same time in one round trip of the material moving structure 10, avoid empty load, reduce the number of movements of the material moving structure 10, thereby improving the efficiency of loading and unloading, allowing the production line to operate efficiently and thus improving production efficiency.

[0031] In the present application, the first material 200 may be a bottom plate 320 for supporting a plurality of film layers 310, and a plurality of film layers 310 such as a bottom protective layer, a dielectric layer, and a surface protective layer may be stacked on the bottom plate 320, the bottom protective layer, the dielectric layer, and the surface protective layer constitute a finished product, and the finished product and the bottom plate 320 constitute the second material 300. That is, in the present embodiment, the feeding device can realize the loading of the bottom plate 320, and at the same time, can also realize the unloading of the finished product and the bottom plate 320 together.

[0032] In some embodiments, Figure 2 and Figure 3 As shown, the material transfer structure 10 includes a connection seat 11 and a support plate 12. The connection seat 11 can be connected to the conveying structure movably up and down. The support plate 12 is installed on the connection seat 11. The top surface of the support plate 12 is used to receive the second material 300 at the first material taking structure 30. The bottom surface of the support plate 12 is provided with a first suction cup structure 13. The first suction cup structure 13 is used to absorb the first material 200 at the first station. It can be understood that the first material 200 is a bottom plate 320. The material of the bottom plate 320 is PET, so the texture is relatively light. Therefore, the first suction cup structure 13 can be directly used to absorb the first material 200. A plurality of film layers 310 are provided on the second material 300. If the suction cup structure is used for absorption, the film layer 310 may be deformed, thereby causing a loss of precision. Therefore, the present application adopts a method of supporting the second material 300 by the top surface of the support plate 12, which can avoid causing a loss of precision of the second material 300.

[0033] In addition, the bottom surface of the support plate 12 may be provided with a plurality of first suction cup structures 13 , which may be arranged in an array and evenly distributed on the bottom surface of the support plate 12 , thereby enhancing the adsorption force and ensuring the stability of the adsorption of the first material 200 .

[0034] Furthermore, the top surface of the support plate 12 is provided with a plurality of blocking blocks 14, which are distributed at the edge of the top surface of the support plate 12. The blocking blocks 14 are used to block the edge of the second material 300, so that the placement of the second material 300 is more stable and avoids separation from the support plate 12 during the movement. Specifically, the support plate 12 of the present application is a rectangular plate-like structure, and the first material 200 and the second material 300 are also rectangular sheet-like structures, so the four corners of the support plate 12 can be provided with blocking blocks 14, and the blocking blocks 14 have two blocking arms, which are respectively used to block the two side lengths of the second material 300, thereby further improving the stability of the placement of the second material 300.

[0035] In some embodiments, Figure 4As shown, the first material picking structure 30 includes a first adsorption plate 31 and a plurality of second suction cup structures 32 connected to the first adsorption plate 31, and the plurality of second suction cup structures 32 are arranged on the periphery of the first adsorption plate 31. Since the second material 300 includes a bottom plate 320 and a plurality of film layers 310 stacked on the bottom plate, and the projection area of ​​the bottom plate 320 along the thickness direction of the bottom plate 320 is greater than the projection area of ​​the film layer 310 along the thickness direction of the bottom plate 320, that is, the edge area of ​​the bottom plate 320 is not covered by the film layer 310, but exposed. The bottom of the first adsorption plate 31 is provided with vacuum adsorption holes, and the first adsorption plate 31 is connected to a negative pressure device, so the vacuum adsorption holes can generate adsorption force, which can be used to adsorb the film layer 310. At the same time, multiple second suction cup structures 32 are used to adsorb the area on the bottom plate 320 that is not covered by the film layer 310. Through the simultaneous adsorption of the second suction cup structure 32 and the first adsorption plate 31, it can adapt to the specific structure of the second material 300 to avoid the separation of the bottom plate 320 and the film layer 310 during the movement of the second material 300.

[0036] Furthermore, the first material taking structure 30 further includes a first mounting plate 33, a first lifting drive member 34, a first lifting plate 35 and a first adapter plate 36. The first lifting drive member 34 is mounted on the first mounting plate 33. The first lifting plate 35 is connected to the output end of the first lifting drive member 34. The first lifting drive member 34 is used to drive the first lifting plate 35 to rise and fall. The first adapter plate 36 is connected to the bottom of the first lifting plate 35. The first adsorption plate 31 is connected to the bottom of the first adapter plate 36. Optionally, the first lifting drive member 34 can be a lifting cylinder or a lifting motor, etc., which is not limited in the present application.

[0037] Furthermore, in some embodiments, the first material picking structure 30 also includes a guide shaft 37, which extends in the vertical direction. One end of the guide shaft 37 is connected to the first lifting plate 35. The first mounting plate 33 is provided with a guide hole. The other end of the guide shaft 37 is movably inserted into the guide hole. The cooperation between the guide shaft 37 and the guide hole can guide the lifting and lowering movement of the lifting plate to prevent displacement.

[0038] Optionally, the number of guide shafts 37 can be set to 4, the first lifting drive member 34 is installed in the central area of ​​the first mounting plate 33, and the four guide shafts 37 are arranged around the first lifting drive member 34, so as to further ensure the guiding effect of the guide shafts 37. Of course, in other possible implementations, the number of guide shafts 37 can also be set to 3, 5, 6 or more, which is not limited in this application.

[0039] Preferably, if Figure 1As shown, the feeding device also includes a second material picking structure 40, and the second material picking structure 40 is arranged corresponding to the first workstation. The second material picking structure 40 is used to grab the second material 300 on the material transfer structure 10 and drive the second material 300 to rise and fall. The first workstation is also used to receive the second material 300 at the second material picking structure 40. Therefore, the first workstation can be provided with a silo to store the first material 200 for grabbing by the material transfer structure 10, and can also be used to receive the second material 300. After the second material picking structure 40 grabs the second material 300 on the material transfer structure 10, the material transfer structure 10 moves away, and the second material picking structure 40 drives the second material 300 to descend, and places the second material 300 on the silo on the first workstation.

[0040] Specifically, Figure 5 As shown, the second material-collecting structure 40 includes a second adsorption plate 41 and a plurality of third suction cup structures 42 connected to the second adsorption plate 41, the plurality of third suction cup structures 42 are arranged at the periphery of the second adsorption plate 41, the bottom of the second adsorption plate 41 is provided with vacuum adsorption holes for adsorbing the film layer 310, and the plurality of third suction cup structures 42 are used to adsorb the area on the bottom plate 320 that is not covered by the film layer 310. It can be understood that the specific structure of the second material-collecting structure 40 is similar to that of the first material-collecting structure 30, so the specific structure of the second material-collecting structure 40 will not be described in detail.

[0041] In some embodiments, the conveying structure includes a translation component 21 and a lifting component 22. The lifting component 22 is movably connected to the translation component 21. The translation component 21 is used to drive the lifting component 22 to move back and forth between the first station and the second station along a first direction. The material transfer structure 10 is connected to the lifting component 22, and the lifting component 22 is used to drive the material transfer structure 10 to move up and down.

[0042] Optionally, the lifting assembly 22 may be a lifting cylinder, etc., and the connection seat 11 of the material moving structure 10 is connected to the output end of the lifting cylinder, thereby driving the material moving structure 10 to move up and down. Specifically, the connection seat 11 may be a triangular plate structure, and since the triangle has stability, the connection between the material moving structure 10 and the lifting assembly 22 can be made more stable.

[0043] Specifically, Figure 2As shown, the translation assembly 21 includes an extension plate 211, a belt transmission structure and a slide rail 212. The extension plate 211 extends in a first direction. The belt transmission structure and the slide rail 212 are mounted on the extension plate 211. The lifting assembly 22 is connected to the belt transmission structure. The belt transmission structure drives the lifting assembly 22 to move in the first direction. The slide rail 212 extends in the first direction. The lifting assembly 22 may be fixed with a slider. The slider cooperates with the slide rail 212 so that the lifting assembly 22 can be slidably connected to the slide rail 212. The cooperation between the slider and the slider can guide the movement of the material transfer structure 10 and make the movement of the material transfer structure 10 smoother. The belt transmission structure includes two pulleys 214 arranged at both ends of the extension plate 211 and a belt 213 wound between the two pulleys 214. The lifting assembly 22 is connected to the belt 213, thereby driving the lifting assembly 22 and the material transfer structure 10 to move.

[0044] Furthermore, the extension plate 211, the belt transmission structure and the slide rail 212 each include two groups, the material moving structure 10 is arranged between the two extension plates 211, and a moving space for the material moving structure 10 is formed between the two extension plates 211. The lifting components 22 correspondingly have two groups, and the two groups of lifting components 22 are respectively connected to the two sides of the material moving structure 10, and the two groups of lifting components 22 are respectively slidably connected to the two groups of slide rails 212, thereby improving the stability of the material moving structure 10 in the horizontal direction, keeping the material moving structure 10 balanced, and preventing the material moving structure 10 from shaking and deviating during the movement.

[0045] In addition, the two opposite pulleys 214 in the two groups of belt transmission structures can be connected by a transmission shaft 215, one of the extension plates 211 is connected to a rotating motor 216, one of the pulleys 214 is connected to the output end of the rotating motor 216, the rotating motor 216 drives one of the pulleys 214 to rotate, and the transmission shaft 215 can transmit the rotational power of one of the pulleys 214 to the other opposite pulley 214, so only one power structure is set up to realize the synchronous operation of the two groups of belt transmission structures, which simplifies the structure of the feeding device and reduces the cost.

[0046] The feeding device of the present application also includes a controller (not shown in the figure), which is electrically connected to the first material picking structure 30, the material moving structure 10, the second material picking structure 40 and the conveying structure, respectively, so that control instructions can be sent to the first material picking structure 30, the material moving structure 10, the second material picking structure 40 and the conveying structure, thereby realizing the cooperation between the first material picking structure 30, the material moving structure 10, the second material picking structure 40 and the conveying structure, which is conducive to realizing automation.

[0047] The utility model also proposes a ceramic capacitor processing equipment, which includes a feeding device. The specific structure of the feeding device refers to the above embodiment. Since the ceramic capacitor processing equipment adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0048] To summarize, the present application sets a transmission structure to drive the material moving structure 10 to move back and forth between the first station and the second station. The material moving structure 10 can grab the first material 200 at the first station and transfer it to the second station, and receive the second material 300 at the second station and then return to the first station. Therefore, the present application can achieve simultaneous loading and unloading of materials in one round trip of the material moving structure 10, avoiding empty loads and reducing the number of movements of the material moving structure 10, thereby improving the efficiency of loading and unloading, allowing the production line to operate efficiently and thus improving production efficiency.
